BMW AG is a well-known and very popular German car manufacturer based in Munich, Bavaria. Together with the companies Audi and Mercedes-Benz, it is included in the so-called large German troika and all cars produced by it belong to the premium class. BMW also owns Mini and Rolls-Royce.
BMW engines, for the most part, are very reliable, quite technologically advanced, durable and have repeatedly received the title of "Engine of the Year". The range of power units is very wide: these are turbocharged three-cylinder B38, four-cylinder (from M10 / M40 and ending with N20 / B48), the legendary BMW in-line six (from M20 / M50 and older, to N54 / N55). Together with the BMW engines of the above-described configurations, for the top models of the company, even larger engines were produced: V8 (from M60 to N63) and V12 for the flagship series. Along with the usual urban versions, a division of BMW M GmbH, sports modifications have been and continue to be produced on the basis of standard power plants... Since 2005, the production of its own M-engines has been launched: the S85 with the V10 configuration, and later its simplified version of the V8 S65. In parallel with gasoline engines, diesel engines were also produced. The family of BMW diesel engines is not so wide: three-cylinder B37, fours M41 / M47 / N47 / B47, sixes M21 / M51 / M57 / N57 and a large V8 M67.
BMW cars have earned the special love of the inhabitants of the CIS countries, so it will not be difficult for the buyer to find a model with a BMW engine of any family, version and modification. And to understand all this diversity, it will not be superfluous to use reviews from Vikimotors.
Below you will find reviews and descriptions of BMW gasoline and diesel engines, old and new, naturally aspirated and turbocharged, conventional and sports M series, their specifications, where they produce, what kind of oil is recommended to pour into the BMW engine. In addition, the main diseases (knocking, oil consumption, power reduction, etc.), shortcomings and problems are described, as well as the repair of BMW engines (gasoline and diesel), tuning, the right approach to increase power and much more.
After reading everything about BMW engines on WikiMotors, you can easily understand which Bavarian model to choose or which contract engine BMW to buy.
With the launch of a new, slightly improved 3-Series, Bayerische Motoren Werke, it has brought some confusion into their ranks. For example, in Europe new model The 330i will replace the previous 328i, but this will happen purely nominally, since the engine will not change its volume and everything will also be represented by 2.0 liters.
I remember there were slightly different times when everything was different. Everything was much simpler and more intuitive. The 328i had a 2.8-liter engine under the hood, and the 330i, of course, had a 3.0-liter engine under the hood. And so on and so forth, at face value.
Logically, such a “forgery” is not accidental and is partly justified. The volumes of motors, of course, are becoming more modest, but the power…, on the contrary, the power is growing, and at a very fast pace. You won't have time to look back, and the new model bypasses last year by a good couple of dozen Horse power... Over the decades of continuous progress, engines that were considered small in the early 90s, 1.6, 1.8 and even 2.0 liter engines now produce more power than that which was developed by 2.5, 3.0, and even 4.0 liter units at the end of the 20th century.
So it turns out that if you count in terms of horsepower under the hood, then some BMW with a "modest" and nothing, not a remarkable 2.0-liter engine can easily make a 4.0-liter monster of the past century according to its peak power. We are generally silent about other important parameters such as reaching peak torque from 1.800-2000 rpm or economy during normal operation.
And to make it psychologically more comfortable for buyers and not to scare away customers with 1.6-1.8 nameplates on the trunk lid, like other leading automakers experimenting with the names of their models, do not write horsepower on the sides, really ?!
To understand the depth of the changes in the BMW engine nomenclature, we will try to find out which Top 5 BMW engines have been installed in 3-Series cars over the years. Including "M" models.
5 - BMW M42 B18, 1.8 liters, inline four, 138 hp from. (E30, E36)
Fifth place was taken by the well-known 1.8-liter BMW unit. Hush, hush, don't drive the horses! We understand that this may not be from Bavaria, but listen to us.
First, where was it used? In the lightweight e30 and e36 bodies, often in the 318iS. We admit, these are not the most best bmw by dynamics and drive (it so happened that BMW owners all as one give this notorious "drive"), but the 1.8-liter engine still fulfilled its mission. Per reasonable price you purchased about sport car with ample opportunities for improvement and dynamics in the stock state just over 10 seconds. For the late 80s, the first half of the 90s, this was a truly valuable breakthrough. The Bavarians brought the feeling of a sports car to the masses. Moreover, everyone could purchase models with this engine without overpayments.
Why didn't the Germans build on the success further and come up with a model for spreading to other continents? The fact was that in South Africa in those years the idea prevailed that cool car must be compact and lightweight and carry the largest available engine in its engine compartment. Needless to say, the coupe still had one temper, not everyone was subject to all the power of this rare nugget.
3 - M47, 2.0 liter, petrol inline four-cylinder, 136 hp. from. (E46)
With this engine, BMW has shown that diesel can be fun. In fact, the 320d, powered by a 134 horsepower 16-valve engine, was faster than the 2.0-liter 6-cylinder 320i petrol model, which had 148 hp. Both cars reached 100 km / h in 9.9 seconds, after which they made themselves felt in torque and the 320d easily bypassed its less agile counterpart.
Soon after its launch, the M47-based 3-Series set a high standard for an affordable, reliable and fuel-efficient sports sedan. Does it sound paradoxical? Perhaps, however, it explains why the 320d models are so successful to this day.
2 - S54, 3.2, in-line six-cylinder, 338 hp (E46)
Okay, stop talking about 1.8 liter engines and diesels, it's time to withdraw the heavy artillery. This 3.2-liter monster that stood on the E46 M3 is undoubtedly one of the best engines BMW ever made. It was based on the M54 DOHC inline six cylinder engine, an aluminum block and a one-piece aluminum cylinder head were used.
He had individual throttle valves for each cylinder, lightweight pistons, larger intake valves, variable valve timing system high pressure high pressure VANOS for variable valve timing, the list of advanced technical solutions is not complete, it can be continued for a long time ...
The S54 is not far from BMW racing engines and was the last naturally aspirated native engine to be fitted to the M3. The power was enough to accelerate the M3 from 0 to 100 km / h in 5.1 seconds, with maximum speed limited at around 250 km / h.
1 - S65, 4.0 liters, 420 hp (E90 / 92/93)
What's the easiest way to design a V8 engine? Well, in the case of BMW, you need to get rid of the two cylinders from the S85 V10 engine. Yes, the V8 version found on the 4th generation M3 is a derivative of the monstrous, F1-inspired road-going V10 that was in production line BMW.
Probably, the debate about which motors will never subside better. All motorists are conventionally divided into several "camps", the largest of which are fans of German, Japanese and American brands. In this article, we will consider the most successful, in our opinion, BMW motors and talk about their reliability.
Among BMW owners you can easily find those who own a car with real mileage more than 500,000 kilometers, you can even find those on the speedometer of which there will be a mark under 1,000,000 kilometers. And this is not a myth, such engines do exist.
We have placed the M57 engine in the category of the best diesel units. This six-cylinder diesel has proven itself to be very reliable and yet quite dynamic. power unit... His merits include a change in the perception of diesel engines as "engines for pensioners", "tractor engines for taxis", etc. A striking example is the BMW 330d in the back of the E46, the dynamics of which was impressive without exaggeration.
The M57 engines were produced from 1998 to 2008 in several modifications with power from 201 to 286 horsepower and were installed on most models of those years. In addition, Range Rover vogue... It is worth noting that the predecessor of the M57 diesel engine, the M51 engine, which stood on the assembly line from 1991 to 2000, did not differ in the same reliability, although it easily “nursed” up to 500,000 kilometers without overhaul.
The next spot on the list is the V-8 M60. It should be noted right away that V8s in the global automotive industry have established themselves as powerful, but not very reliable engines that can hardly “reach” without major repairs to a mileage of 500,000 kilometers. However, in the case of the M60, BMW has made a breakthrough. Timing with a double-row chain, careful design and special nickel-silicon ("Nikasil") sputtering of the cylinders provided the engine with a long service life. There are documented cases when, with runs close to 500,000 kilometers, during its disassembly and defecting, it was not even necessary to replace it. piston rings... Of course, time takes its toll, and today it is quite difficult to find a "live" motor of those years, but it is still real. During the operation of these engines, BMW decided to abandon the Nikasil coating, which turned out to be sensitive to sulfur impurities in the fuel, in favor of the improved Alusil coating. The M60 engines were produced from 1992 to 1998 and were installed in the BMW 5 and 7 Series.
Most motorists associate the phrase "in-line six" with BMW. And one of the representatives of such engines, distinguished by their reliability, is the M30, the first modification of which was released back in 1968 and later was on the conveyor until 1994.
The power of the M30 engine ranged from 150 to 220 horsepower with a working volume of 2.5 to 3.0 liters. The reliability of this motor is explained by the simplicity of its design: a timing chain drive, a cylinder block made of cast iron, an aluminum cylinder head with two valves per cylinder. The safety margin of the M30 engine allowed the Bavarian engineers to make its turbocharged version of the M102B34, the power of which was 252 horsepower. To do this, the engine required a minimum amount of modifications.
M30 engines were equipped with several generations of BMW 5 and 7 Series. With proper maintenance, these motors can easily travel up to 500,000 kilometers without major repairs.
The successor to the M30 was the most "legendary six" - the M50. The working volume of this engine ranged from 2.0 to 2.5 liters, and the power from 150 to 192 horsepower. Just like its predecessor, the cylinder block of this power unit was cast iron, and 4 valves per cylinder were used in the design of the aluminum cylinder head. In addition, later versions of the M50 engine began to be equipped with a Vanos valve timing system. Just like the rest of the motors from this article, with timely maintenance, the M50 can easily "nurse" up to half a million kilometers without major repairs. The new generation of this engine, which received the M52 index, despite its more complex design, retained its reputation as a reliable unit, but, as time has shown, it loses to its predecessor in terms of resource and the number of breakdowns.
As for modern turbocharged BMW engines, it is perhaps too early to single out the favorites among them ...
This review presents gasoline and diesel engines BMW used for the last 15 years. Due to the huge range of power units of the Bavarian company, we cannot cover all engines and their variants. Nevertheless, let us take a closer look at the most famous and popular motors.
BMW is one of the world's leading manufacturers offering the most modern and advanced powertrains on the market. Therefore, you need to be prepared for high maintenance and repair bills. There is no need to look far for examples - for many owners it comes as a surprise that the timing chain drive, used in all modern BMW engines, needs to be periodically replaced. The chain and tensioner, as a rule, maintain about 200-300 thousand km. At the same time, noise appears, and the engine runs unevenly. To replace the timing chain, it is necessary to prepare about 20-30 thousand rubles. In the case of old copies, difficulties arise when trying to conduct overhaul- the materials used for the manufacture of cylinder liners do not allow them to be refurbished.
How much you will spend after buying a used BMW depends on the condition of the vehicle and the engine version under the hood. Our review will certainly help to make right choice.
Engine marking
German concern BMW has been one of the leaders in production for many years automotive engineering, parts and assemblies. BMW engines are no exception. The line of power units of this company is quite large. To identify a specific series of motors, the letters are used:
- M - for standard serial motors;
- S - for Motorsport sports engines;
- N - for modern engines new generation;
- P - for prototypes.
It is worth noting that the BMW engines used in the second generation X5 model are classified N, which indicates the use of innovations and the latest developments. Modern models X5 is equipped with several types of supercharged gasoline and diesel engines.
M21 2.5 liter engine (diesel) 82-91 (E28, E30)
The M21, a 6-cylinder diesel engine, was the first diesel in BMW's history. Production began in 1982 to fit the 524td in the newly introduced E28 body. The M21 was equipped with a turbocharger, which allowed the diesel version to retain the image of a dynamic machine inherent in all BMW models... With the release of the new E30 3 Series bodywork, the M21 has another application, the 324td.
In 1985, an attempt was made to produce an economical version without turbocharging. But the leisurely 524d and 324d did not appeal to buyers. The very next year, the production of naturally aspirated diesel engines was discontinued and never resumed.
2.5, 2.8, 3.0, 3.2, 3.5 liter M30 engine
Concern BMW lured Bernard Oswald from Ford to develop the second generation of six-cylinder engines in the mid-sixties. The first were six-cylinder engines with seven crankshaft bearings. They were used in the new sedans of the E3 series in 1968. The successful M10 formula was reapplied - cast iron block, aluminum head with chain driven camshaft. After 1972, the development took place under the control of Gustav Ederer and it was then that the first model with 4 valves appeared - the M88
The M30 engine is a large inline 6-cylinder engine with 2.5, 2.8, 3.0, 3.2 and 3.5 liter displacement. It can be found on the 5 Series (E12, E28 and E34), 6 Series (E24) and 7 Series (E23 and E32), as well as the famous BMW M1.
The engine turned out to be very successful, both in design and in survivability. Of course, partly the survivability of the engine was provided by its high power. Due to the fact that more powerful engines and load less.
Only the modification of the M30B35 with a cylinder diameter of 93.4 mm was unsuccessful - it turned out to be too energy-loaded. But do not confuse it with the M30B34, which was installed on almost all 3.5 liter cars.
The M30 is an engine for a quiet ride, it has a too heavy piston and too large piston strokes, which do not allow it to spin up quickly and create heavy loads on the bearings (liners).
Also, due to the high mass of the piston system, the engine is very picky about oil if it is fed. mineral oil and at the same time constantly keep it in the range of revolutions of 4-6 thousand, after a few thousand you will have to grind the crankshaft. Only synthetic oil needs to be poured into this engine, and if you like to turn it, then at volumes of more than 2.8 liters, the installation of an oil cooler is required.
On the other hand, the advantages of in-line six balance and high power for low revs more than compensate for these shortcomings.
Also M30 - was the second and last engine on which turbocharging was serially installed - the turbocharged modifications of the M30 were used only in the 745i models in the E23 body. In fact, their volume was 3.2 and 3.4 liters, depending on the modification. But both variants were marked M102. The power is the same - 252 hp. The main difference is the ignition and power system.
The engine was installed on cars of the third, fifth, sixth and seventh series.
3rd series:
E30 - 333i - 3.2. liters, with the Motronic injection system. Supplied only to the UAE.
5th series:
E12 - 525 - 2.5 liters with carburetor, 528 - 2.8 liters. with carburetor and injector, 535i - 3.5 liters, with injector only.
E28 - models 525i, 528i, and from 1985 535i and M535i. Starting with the E28 body, only injection modifications were installed.
E34 - 530i - 3L, 535i - 3.5L Also, only an injector with a Motronic injection system and a crankshaft position sensor located on the crankshaft damper, and not on the gearbox.
6th series:
E24 - 628CS with carburetor and injection (628CSi), 633CSi, 635CSi - injector only. 
7th series:
E23 - 728 injector / carburetor, 730 carburetor, 732i / 733i, 735i, 745i - turbocharged version of the engine was installed on the 745i model.
E32 - 730i, 735i - 3.0 and 3.5 liters, respectively.
BMW M47 - in-line 4-cylinder diesel engine
First released in 1998, the M47D20 boasted 100 kW (136 hp) of power and 280 Nm (207 ft-lb) of torque in the 320d / 520d variant, and 85 kW (114 hp) with 265 Nm (195 ft-lb) of torque. ) performed by 318d. All M47 engines have one valve and one vortex injector per cylinder, each of which can improve performance in a variety of conditions. The M47diesel was equipped with an indirect fuel injection with an engine displacement of 1951 cc.
Initially, thermostats were installed on all BMW engines of that time, which, when worn out, caused additional cooling of the engine, which deteriorated the engine's fuel consumption characteristics. Later the BMW plant changed fuel system engine on a single row high pressure system.
Diesel BMW engine The turbocharged M47 uses a Garrett variable geometry turbocharger (VGT), also known as a variable vane turbocharger. These early VGTs used until September 2003 vacuum system to control the drive, which in turn controls the movement of the blade. Over time, the drive vacuum tubes are prone to deterioration, which can affect the operation of the entire turbocharger. Later turbochargers (after September 2003) are electronically powered and failure can lead to costly replacement of both the compressor and the entire drive. Fortunately, in some cases the actuator can be repaired separately without replacing the turbocharger.
To help keep the turbocharger and engine in top condition, regular replacements are imperative. synthetic oil and filters after a run of 7000-8000 km. Regular checks are also required. plastic parts oil separator or replace them every 12-18 months in order to avoid clogging and increase in internal pressure.
If your turbocharger has failed on this engine, and the scan cannot reveal specific error codes, then you can check all the vacuum tube connections and the condition of the vacuum reservoir itself. To do this, simply disconnect the vacuum hose.
The whistle of the engine turbine is another unpleasant sign inherent in this engine. Some turbos whistle more than others, and this may simply be a characteristic of general engine wear. If the sound resembles a police siren, then we advise you to check the clearance on the turbine shaft as soon as possible.
To access the compressor shaft while the engine is cool, remove the air duct and pinch the shaft between your thumb and forefinger. This way you can check how much the bearings "float", both from side to side (radial clearance) and axially (axial play). The axial clearance is usually between 0.025–0.1 mm and can hardly be felt, the radial displacement is usually between 0.3–0.6 mm. For more accurate measurements, a dial gauge is required. But if the "floating" movement seems excessive, then most likely immediate repair is required. 
Unusual high consumption oil combined with blue smoke from the flue pipe can be a symptom of worn seals. On very rare occasions, the engine may run on its own oil, causing plumes of smoke. If this happens, turning off the ignition may be pointless as it burns motor oil which can lead to engine seizure. Try to use the clutch to brake the car with your feet on the brake.
The M47 motor for its time was the best in technical characteristics in its class. At the same time, it has a number of features that entail an increase in service costs. However, compared to its N47 successor, it is a less problematic and generally more successful engine. It can be argued that this is a very successful motor, although it is not necessary to rely on a low operating cost.
BMW engine: diesel unit
The small letter D in the name of the BMW model means significantly great results... Every BMW diesel engine, whether four, six or eight cylinders, guarantees refined power and superior fuel efficiency. Improved turbochargers, revised turbine geometry and direct injection have given the diesel engine a new look.
The price for such innovations: 306 liters. from. power at a flow rate of not more than 7.5 liters per 100 km. Acceleration at the same time to hundreds is only 6.6 seconds. Regardless of which engine is installed in the BMW X5, there is one thing you can always be sure of - maximum driving comfort combined with maximum performance.

BMW was the first German manufacturer to release a V12 engine in 1986, forcing Mercedes-Benz to follow suit in 1991. Only 7 and 8 Series cars used V12 engines. While BMW sells much fewer cars with a 7 series V12 engine than the V8 version, the V12 retains its popularity in the USA, China and Russia, and also maintains the prestige of this luxury car brand.

BMW engine number decoding
Decoding and designation of the BMW internal combustion engine by engine model:
- family of engines, mainly denoted by the letter:
- M - engine developed before 2001;
- N - engine developed after 2001. Beginning in the early 2000s, BMW revised its naming strategy to make it easier to understand and more detailed information about updates in the motor. New to the N Series engines is a new design, material of manufacture of parts and technology used in the motor itself;
- B - modular engine. Since 2013 BMW company began to introduce a new family of modular motors. The first cars to receive the new "B" series engines were a hybrid sports car and the lineup compact Mini. Both of these cars were powered by a B38 3-cylinder turbocharged - direct injection - Valvetronic engine. The B Series modular engine family includes gasoline and diesel powertrains that share common components and architecture (60% of the parts are identical, for example, a 3-cylinder engine has components from a 4-cylinder B Series engine). The volume of the engine increases in steps of 500 cubic centimeters - 1.5l - I3, 2.0l - I4, 2.5l - I6, 3.0l - I6, etc .;
- S - BMW Motorsport engine;
- P - BMW Motorsport racing engine;
- W - engine from a "third-party" developer;
- number of cylinders, indicated by a number:
- 1 - in-line 4-cylinder;
- 2 - in-line 4-cylinder;
- 3 - in-line 3-cylinder;
- 4 - in-line 4-cylinder;
- 5 - in-line 6-cylinder;
- 6 - V-shaped 8-cylinder;
- 7 - V-shaped 12-cylinder;
- 8 - V-shaped 10-cylinder;
- a change in the basic concept of the engine, where:
- 0 - base engine;
- 1-9 - changes to the original design, such as the combustion process;
- fuel type:
- B - gasoline;
- D - diesel;
- E - electric;
- G - natural gas;
- H is hydrogen (hydrogen);
- engine displacement in 1/10 liters (indicated by two numbers), for example:
- 15 - 1.5 liters;
- 20 - 2.0 liters;
- 35 - 3.5 liters;
- 44 - 4.4 liters;
- letter designation
- power class:
- S - "super";
- T - top version;
- O - "top exit";
- M - "medium exit";
- U - "lower output";
- K - "lowest output";
- O - new development;
- TU - this designation is indicated only in M-Series engines and indicates a significant upgrade, for example - from one to double VANOS;
- or a type test requirement (changes that require new type tests):
- A - standard;
- B-Z - as required, for example, ROZ 87;
- power class:
- technical version for designation in BMW motors, except for M series engines and replaces the previous TU suffix:
- from 0 to 9;
BMW also has a different numbering system for internal production and use. This code, printed on the side of the cylinder block, is used at the BMW assembly plant and during other maintenance when it comes to the actual identity of the engine. In most cases, this code is applied to the flat section of the block on the driver's side.
For example "30 6T 2 04N", where:
- 30 - engine volume 3.0 liters;
- 6 - six-cylinder engine;
- T - engine type, in this case a power unit with a turbine;
- 2 - index of differentiation;
- 04 - revision number, in this case 4th;
- N - new engine;
The marking is also found on older models, for example - 408S1, where:
- 40 - engine volume 4.0 liters;
- 8 - number of cylinders;
